Question

7+X/5 - 2x-y/4=3y-5​

Answer 1

${ \bf{ \huge \underline{soluion \colon}}}$

${ \rm{ \large {7 + \dfrac{x}{5} - 2x - \dfrac{y}{4} = \dfrac{3y}{5} }}}$

$\implies{ \rm{ \large {7 + \dfrac{x}{5} - 2x = \dfrac{3y}{5} + \dfrac{y}{4} }}}$

${ \rm{ \large { \implies\dfrac{35 + x - 10x}{5} = \dfrac{12y + 5y}{20} }}}$

${ \rm{ \large { \implies\dfrac{35 - 9x}{5} = \dfrac{17y }{20} }}}$

${ \rm{ \large { \implies5 \times 17y = 20(35 - 9x)}}}$

${ \rm{ \large { \implies85y = 700 - 18x}}}$

${ \rm{ \large { \implies85y + 18y= 700}}}$
